An irrigation runoff study on a residential lawn was conducted in California, northeast of Sacramento, during the summer and fall of 2008 to investigate the contribution of turf uses of pyrethroids to residues in Californian urban creek sediments. This study examined how over irrigation (i.e., irrigation that produces runoff) in the summer season may transport recently applied pyrethroids. The ...

In order to protect the environment and groundwater against pollution, we dealt with one of problems in world, regarding treatment wastewater possibility reuse irrigation. We studied case Kef Eddouken natural lagoon plant Ghardaia (southern Algeria). For this reason physico-chemical, bacteriological parsitological parameter waste treated water. The results analysis show that all previous parame...

The double stapling technique is indispensable in low anterior resection for colorectal cancer. However, to prevent local recurrences due to the driving of cancer cells into the anastomosis. Intraluminal lavage should be performed.

for identifying drought tolerance genotypes 29 wheat genotypes as cultivar factor and irrigation and non irrigation treatments as an irrigation factor in a split block design with 3 blocks were planted at a research filed of college of agriculture, tehran university, iran. there was a low and non significant correlation (r=0.35) between yield at non irrigating (ys) and yield at irrigating (yp) ...

Rice is an essential crop in Iran that is grown mostly in areas where depth to groundwater is low. Root growth and water uptake of rice under shallow groundwater has not been thoroughly studied. This experiment was conducted to determine the lowland rice (cv. Ghasrodashti) root distribution above shallow groundwater in relation to deficit irrigation and groundwater depth in cylindrical gre...

Drip irrigation control systems in fields generally include a large number of sensors and valves; controlling these devices efficiently can be achieved by using distributed irrigation control (DIC), which has the advantages of reduced wiring and piping costs and easier installation and maintenance. In this study, a wireless low power valve controller for drip irrigation control systems was deve...

Site-specific irrigation is defined as delivering different prescribed depths of water to specific areas in irrigated fields. Since the 1990s, site-specific irrigation research has been expanded to include the delivery of water and nutrients to specific field areas based on soil type, soil moisture status, crop needs, and other user-defined objectives. A site-specific center pivot irrigation sy...

We call a Gromov-Hausdorff limit of complete Riemannian manifolds with a lower bound of Ricci curvature a Ricci limit space. In this paper, we prove that any Ricci limit space has integral Hausdorff dimension provided that its Hausdorff dimension is not greater than two. We also classify one-dimensional Ricci limit spaces.
